[Bug]: GetAsync in WebAPI.cs doesn't return response correctly in MAUI environment

[alexp9982]

What did you expect to happen?

I test my code on a Console App before putting code in my MAUI application, and the code works perfectly there.

Instead of that, what actually happened?

However, when I put the nearly exact same code in my MAUI application found here, the application becomes indefinitely frozen. I traced this back to the GetAsync method in the WebAPI.cs file. The method calls GetAsyncInternal, which returns a response object. The return statement gets called, but for some reason, in the MAUI application, after the return statement runs, this is where the application starts hanging.

Example Code

try
        {
            KeyValue ownedGames;
            if (user1a.Length == 17 && user1a.All(char.IsDigit))
            {
                using (dynamic playerService = WebAPI.GetInterface("IPlayerService", apikeya))
                {
                    ownedGames = playerService.GetOwnedGames(steamid: Convert.ToUInt64(user1a),
                        include_appinfo: true, include_played_free_games: true);
                }
                var gameCount = ownedGames[ "game_count" ].AsString();
                if (string.IsNullOrWhiteSpace(gameCount))
                {
                    StatusText = "";
                    InvalidText = "User 1 is not valid or has no games, ensure User 1 is correct and try again";
                    ButtonEnabled = true;
                    return;
                }
            }

            else
            {
                string user1AsString;
                using (dynamic steamUser = WebAPI.GetInterface("ISteamUser", apikeya))
                {
                    KeyValue steamId = await steamUser.ResolveVanityURL(vanityurl: user1a);
                    user1AsString = (steamId[ "steamid" ].AsString());
                    if (string.IsNullOrWhiteSpace(user1AsString))
                    {

                        ButtonEnabled = true;
                        return;
                    }
                }

                using (dynamic playerService = WebAPI.GetInterface("IPlayerService", apikeya))
                {
                    ownedGames = playerService.GetOwnedGames(steamid: Convert.ToUInt64(user1AsString),
                        include_appinfo: true, include_played_free_games: true);
                }

                var gameCount = ownedGames[ "game_count" ].AsString();
                if (string.IsNullOrWhiteSpace(gameCount))
                {
                    StatusText = "";
                    InvalidText = "User 1 has no games, ensure User 1 is correct and try again";
                    ButtonEnabled = true;
                    return;
                }
            }

            foreach (var userGames in ownedGames[" games "].Children)
            {
                user1Games.Add(userGames[" name "].AsString());
            }
        }
        catch (Exception e)
        {
            Debug.WriteLine(e);
            StatusText = "";
            InvalidText = "Your API key is not valid. Ensure you followed the instructions correctly and try again";
            ButtonEnabled = true;
            return;
        }

Additional Information

The entire project is open source, and the example code above is available in this file.

Currently in the process of seeing if this API can replace the old API I'm using, which is why the link above uses the new-api-testing branch. It's possible that I'm doing something wrong, but considering the code works in a console app, I'm very confused if I am doing something wrong. Thank you for looking at this problem. I am willing to provide as much information as possible, including debugging steps.

If I'm interpreting the bug description correctly, you're hanging on await CallAsyncInternal, which suggests a threading problem, potentially a deadlock.

Yes, sounds about right. Would you like me to record a video of what happens?

Edit: Also to clarify, I don't know of it's the CallAsyncInternal, or CallAsync that is causing the problem, since the hanging begins at the return line of the CallAsyncInternal. Thought I'd clarify that since I read the bug report again and realized I never mentioned which method's return statement it got stuck on.
